WILLARD J. WOODCOCK, OF BROOKLYN, NEW YORK, ASSIGNOR TO VVOOD- COCK PLATE ICE COMPANY, A CORPORATION OF NEW JERSEY.

ART OF PRODUCING PLATE-ICE.

SPECIFICATION forming part of Letters Patent No. 745,549, dated. December 1, 1903.

' Application filed November 10, 1902. Serial No. 130,655- (No specimens.)

To all whom it may concern:

Beit known that I, WILLARD J. Wooncoou, of Brooklyn, Kings county, New York, have invented a new and useful Improvement in the Art of Producing Plate-Ice, of which the following isa specification.

The invention relates to an improvement in the art of producing plate-ice; and it consists in congealiug said ice at a temperature below 0 Fahrenheit in contact with a yielding surface.

In the accompanying drawings, Figure l is a transverse section of a refrigerating vessel containing a freezing-plate with ice formed thereon. Fig. 2 is a longitudinal section of the same, showing the water-level lowered and the ice broken away to exhibit the yielding surface of said plate.

Similar letters of reference indicate like parts.

In Letters Patent No. 682,659, granted to me September 17, 1901, I have shown, de scribed, and claimed a stable freezing-plate having a yielding surface to compensate for the expansion and contraction of the ice forming thereon. I have discovered that when ice is produced upon such yielding sur face at temperatures below 0 Fahrenheit, even down to 60, it is not only much more rapily formed than at temperatures above 0, but is produced free from cracks and in a perfectly clear state.

Referring to the drawings, A is a refrigerating vessel containing water I. B is a hollow freezingplate disposed therein. I The 3 5 freezing medium, such as brine, at a temperatu re below 0 Fahrenheit is led into said plate by pipe C and escapes by pipe D. Said plate has yielding surfaces upon which the ice G H forms from the water I. Said yielding sur- 40 faces may consist each in a layer of sheathing J, of rubber or other suitable material, applied to the plate B.

I claiin 1. The process of producing plate -ice,which consists in freezing water at a temperature below 0 Fahrenheit while permitting the ice block during its formation freely to expand and contract.

2. The process of producing plate-ice which consists in freezing water at a temperature below 0? Fahrenheit while causing the ice to form upon a support free to yield with the expansion and contraction of said ice.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLARD J. WOODCOCK.
